100 HeartsRepresenting 100

This 100th day idea can double as a Valentine’s Day

display. With students’ help, determine how the class

will share the responsibility of using several templates

to make 100 identical construction paper hearts. Once a

plan is made, ask the youngsters to complete the task.

Then use a similar plan to have students label the hearts

with things or activities that they like. Have students glue

the prepared hearts onto a jumbo heart-shaped wreath

that you have cut from bulletin board paper. Display the

wreath with a desired title for the 100th day and plan

to update the title for Valentine’s Day. Not only will the

wreath represent 100, but it will also be an eye-catching

reminder of the value of teamwork!

A Day to Celebrate!

There’s no doubt about it—the 100th day of school is cause

for celebration! To recognize the day in grand style, present

each youngster with a copy of the badge on page 4 to color,

cut out, and wear. Use one or more of the activities below

to make math time extra special. Then, for a sweet finale,

invite each youngster to prepare a snack by using a tube of

decorating gel to label a cupcake or cookie “100.”

• …98, 99, 100! Challenge groups of students to create

posters for the day’s events. The catch? Each poster needs

to have 100 letters, words, or illustrations! Counting to 100

• More or Less? In each of four clear plastic containers,

place a quantity of items that is more or less than 100.

Letter each jar. Then have each child complete an

estimation form similar to the one shown. Ask volunteers

to count the items and announce the actual counts.

Estimating

• Tens Mystery Program large blank cards by tens from 10

to 100. Randomly give the cards to ten students and ask

them to line up in numerical order. Next, have the seated

students cover their eyes. Silently signal one cardholder to

step aside and conceal her number. Then ask the seated

students to study the remaining cardholders and guess the

missing number. To reveal the answer, have the chosen

cardholder return to her position and display her number.

Continue with different numbers and volunteers as time

allows. Using number patterns100th Day Estimates

Impressive Collections

Representing 100 with concrete objects, skip-counting

The 100th day of school calls for counting possibilities by the

hundreds! A few days in advance, give each youngster a copy

of the poem on page 4 and read it aloud. Guide students to

brainstorm 100 similar items that they might find at home, such

as paper clips or cereal pieces. Then have each youngster cut

out his poem and glue it onto a personalized paper lunch bag.

Ask him to use the bag to bring in a collection of 100 items.

On the designated day, have each student use a large sheet

of construction paper to display his collection on his desk or

another work surface. Invite students to walk along an estab-

lished classroom path to view their classmates’ collections.

Next, instruct each student to arrange and count his items in

sets of ten. Ask him to repeat the process with sets of five. So

that’s what 100 looks like!

Use these festive ideas to celebrate the 100th day of school, and math

reinforcement will be a “shear” delight!

Counting Sheep

Using number order and number patterns

Counting sheep has new meaning with this woolly hundred

chart! Post a large piece of bulletin board paper within student

reach. Copy the patterns on page 4 to make 100 sheep and

distribute them to students. After the youngsters color the hats and

cut out the cards, help them glue the sheep onto the paper in ten

rows of ten. Then lead students in counting the sheep by tens.

To follow up, use a colorful marker to label the first sheep

“1” and the last sheep “100.” Number a selected sheep in each

remaining row. Label several sticky notes with other numbers

between 1 and 100. Give a volunteer a sticky note; then have her

read the number aloud and adhere it to the appropriate sheep. Ask

her to explain her strategy for determining the correct placement,

such as counting back or using a number pattern. Invite the other

students to identify different strategies. Continue with the remaining

sticky notes in a similar manner. For additional reinforcement,

arrange for the display to be a learning center option.

How to Use Pages 11 and 13

Invite youngsters to help the sleepy bear count his 100

slippery snacks! Give each child a copy of the page. Have

her color the page and then cut out the two picture

strips. Help her glue the strips together where indicated.

Guide her to count by tens as she points to each set of

fish. Then help her write the missing numbers in the

spaces provided.
